[edit] Member functions

(constructor) [deleted]	has neither default nor copy constructors (public member function)
operator= [deleted]	can not be copy-assigned (public member function)
operator== operator!=	checks whether the objects refer to the same type (public member function)
before	checks whether the referred type precedes referred type of another type_index object in the implementation defined order, i.e. orders the referred types (public member function)
hash_code (C++11)	returns a value which is the identical for the same types (public member function)
name	implementation defined name of the type (public member function)
